With autumn just around the corner, have you started thinking about what flowers to plant in your garden? If not, spider mums should be at the top of your list. These beautiful flowers bloom in a variety of colors and can be used for decoration or for creating a vibrant autumnal atmosphere in your garden. In this blog post, we will discuss how to grow spider mums in detail, including how to plant and care for them.
Spider Chrysanthemums, formally known as Chrysanthemum x morifolium ‘Spider’, are a unique variety distinguished by their long, tubular petals that curve and twist, giving the appearance of a spider’s legs. This dramatic bloom style, combined with an extensive color range, from whites, yellows, and oranges to purples, pinks, and reds, make Spider Chrysanthemums a striking addition to any garden or floral arrangement.
How to Grow Spider Mums – Zone and Soil Prep
Spider mums thrive in USDA hardiness zones 5-9, making them quite adaptable to various climates. They prefer full sun exposure and require well-draining soil to prevent root rot and other related issues.
When preparing your garden for planting, choose a location that receives at least six hours of sunlight each day. The soil should be rich in organic matter, and it’s beneficial to amend it with compost or a slow-release fertilizer before planting to provide nourishment to your spider mums. Ensure the soil pH is neutral to slightly acidic, ideally in the range of 6.5 to 7.0, for optimal growth. Soil testing kits are widely available to help you check and adjust your soil’s pH level as needed.
Light and Water Requirements
Spider mums need ample sunlight to thrive. Ensure they receive at least six hours of sunlight each day. If you live in a region with a hot climate, you may want to consider providing afternoon shade to protect the plants from scorching midday sun.
In terms of watering, these plants prefer evenly moist soil, but never waterlogged. It’s recommended to water them deeply once or twice a week, rather than frequent shallow watering, to encourage the development of a robust root system. Remember, the top one inch of soil should dry out between watering, as overwatering can lead to root rot. In drier climates or during hot weather, you may need to water more frequently. Always water at the base of the plant to avoid wetting the foliage, which can lead to fungal diseases.
Fertilizing and Deadheading your Spider Mums
For fertilizing your spider mums, it is best to use a balanced all-purpose granular fertilizer with a ratio of 10-10-10 or 14-14-14. Fertilize your plants once a month from spring until mid-summer to promote vigorous growth and blooming. Always follow the manufacturer’s instructions when applying fertilizer. Over-fertilizing can lead to burnt foliage and can decrease the plant’s resistance to pests and diseases.
Deadheading, the practice of removing spent blooms, is another crucial aspect of spider mum care. Not only does it maintain the plant’s appearance, but it also encourages the growth of more flowers. To deadhead your spider mums, simply pinch or cut off the faded blossoms at their base. Be careful not to damage the nearby buds and leaves. If you continue this practice throughout the blooming season, your spider mums will continue providing a vibrant display of color throughout autumn.
How to Grow Spider Mums – Preparing them for Winter
As winter approaches, it’s essential to prepare your spider mums adequately to ensure their survival and blooming in the following season. When the first hard frost is in the forecast, it’s time to get your spider mums ready for dormancy.
Start by cutting back the stems of your spider mums to about 3-4 inches above the ground after the first frost kills off their foliage. This helps to protect the crown of the plant, where next year’s growth will begin. After cutting back the plant, clear away all the trimmed stems and any other plant debris from the area to avoid attracting pests or diseases.
Next, apply a thick layer of mulch, about 2-3 inches deep, over the entire planting area. The mulch serves a dual purpose – it helps to protect the plant’s root system from freezing temperatures and also enriches the soil as it breaks down over the winter. Use organic mulch like straw, shredded leaves, or pine needles for this.
While spider mums are hardy in zones 5-9, in the colder end of this range (zones 5 and 6), you may want to consider additional winter protection. One common method is to build a simple chicken wire cage around each plant and fill it with straw or shredded leaves for insulation. Remove the cage and the insulation in early spring before new growth begins.
By taking these steps, you can help your spider mums survive the winter and return with a bounty of beautiful blooms the following year.
How to Grow Spider Mums in Pots
Growing spider mums in pots on your patio is a great way to enjoy these vibrant flowers without needing a large garden space. Choose a large pot, at least 12 inches in diameter, with adequate drainage holes to prevent waterlogging. Fill the pot with well-draining potting soil mixed with compost or slow-release fertilizer to provide nutrients.
Plant your spider mums in the pot, ensuring the crown of the plant is level with or slightly below the soil surface. Firm the soil around the plant and water thoroughly. Place the pot in a location on your patio that receives at least six hours of sunlight daily.
Remember, spider mums in containers will require more frequent watering and feeding compared to those in the ground. Water them when the top inch of soil feels dry to the touch. Feed them with a balanced all-purpose fertilizer once a month during the growing season, following the manufacturer’s instructions.
Deadhead faded blooms regularly to keep your potted spider mums looking their best and to encourage more flowers. As winter approaches, move your pots to a protected location, such as an unheated garage or basement, to safeguard them from freezing temperatures. If you can’t move your pots indoors, wrap them in burlap or bubble wrap for added insulation, and ensure the plants are well mulched.
Happy Gardening!
In conclusion, spider mums are a gorgeous addition to any autumn garden. These flowers brighten up any space and provide a welcoming and inviting environment. If you’re planning on growing spider mums in your garden, remember to give them well-draining soil, full sun with partial shade, regular watering, and proper fertilization. Being careful to pinch back the tips of your spider mum and use pesticides in case of pest infestation is also important. With these tips in mind, get ready to enjoy the vibrant, beautiful blossoms of spider mums in your garden this season!
